Detailed explanation-1: -The first step in photosynthesis is the photo excitation of chlorophyll by a photon of light.
Detailed explanation-2: -The first process of this process is to entrap light. This step occurs as light reactions that involve photophosphorylation reactions involving photosystems I and II. The entrapped light is used in the formation of energy such as ATP and NADH. This energy is used to process various biosynthesis reactions.
Detailed explanation-3: -Photosynthesis takes place in two stages: the light-dependent reactions and the Calvin cycle. In the light-dependent reactions, which take place at the thylakoid membrane, chlorophyll absorbs energy from sunlight and then converts it into chemical energy with the use of water.
Detailed explanation-4: -Hence, the first step in photosynthesis is the “excitement of an electron of chlorophyll by a photon of light."
Detailed explanation-5: -Process of Photosynthesis Step by Step The sunlight is absorbed by the chlorophyll in the leaves of the plants. Carbon dioxide enters the plant through structures called the stomata, which are usually found on the underside of the leaves. Water is absorbed through the roots of the plant.
